Bear Creek Arsenal / Radical RF-15 .50 Beowulf Rifle – 16" Right-Side Charging Upper, M-LOK Handguard, Muzzle Brake

This rifle is a hybrid build using a Bear Creek Arsenal upper chambered in 12.7x42 / .50 Beowulf on a Radical Firearms RF-15 lower. From the photos, it appears to be the right-side charging configuration with a long M-LOK handguard, full top rail, flip-up sights, and a large brake at the muzzle. The all-black setup gives it a clean, aggressive look, and the heavier big-bore chambering makes it appealing to buyers who want something substantially different from a standard AR-15. The upper markings visible in the photos also line up with Bear Creek Arsenal branding.

Bear Creek Arsenal’s current .50 Beowulf-pattern upper listings show this format as a 16-inch parkerized heavy barrel with 1:20 twist, carbine-length gas system, 15-inch M-LOK rail, and right-side charging handle. BCA also notes these 12.7x42 uppers are compatible with mil-spec AR-15 lowers, which fits the configuration shown here. Radical’s complete lower listings describe a forged 7075-T6 aluminum lower with black hardcoat anodizing, an AR-15 pattern setup, and collapsible stock furniture.
